Method of formulating input parameters of neural network for diagnosing gas-turbine engines
Aviation, 2013 A method of obtaining test and training data sets has been developed. These sets are intended for training a static neural network to recognise individual and double defects in the air-gas path units of a gas-turbine engine.

Titanium in the Gas Turbine Engine [PDF]
, 2011 The development of the gas turbine engine over the past 60 years has been mirrored by the success of the titanium industry, with a clear symbiant relationship existing between the two industries. Immediately apparent in the early days of the evolution of the gas turbine was the need for a material which could provide the strength required for component

The CW251B12 Gas Turbine Engine [PDF]
Volume 4: Heat Transfer; Electric Power; Industrial and Cogeneration, 1989 The latest variant of the W251 family of engines, the CW251B12, rated at 48 MW, is described in this paper. The improved performance, compared to the CW251B10 model, is achieved by the redesign of the compressor for increased mass flow and efficiency and by hot end modifications, which allow a modest increase in firing temperature.
